From ac646f44956edc9aaa406b4a8fef17888a2166af Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Sun, 19 Oct 2025 10:40:08 +0200 Subject: [PATCH] genirq/msi: Slightly simplify msi_domain_alloc() The return value of irq_find_mapping() is only tested, not used for anything else. Replaced it by irq_resolve_mapping() which is internally used by irq_find_mapping() and allows a simple boolean decision.
